DESIGN, DEVELOPMENT AND INSTALLATION OF 100KW UTILITY AND GRID CONNECTED SOLAR PV POWER PLANTS FOR RURAL APPLICATIONS-AN INDIAN EXPERIENCE

摘要

Two 100KW Solar Photovoltaic Power Plants have been installed in the State of Uttar Pradesh (UP), India, by Central Electronics Limited (CEL)for the Non-Conventional Energy Development Agency (NEDA) of UP. In the absence of prior experience on such large capacity Solar PV Power Plants, an experimental pilot PV power plant of 25 KW capacity was installed in CEL to gain hands-on experience and the lessons learnt were made use of while installing the two power plants. This paper briefly describes the features of the two power plants, the developmental approach adopted based on "Building Block Philosophy " with 25 KW System as the basic unit with the attendant advantages. It includes the indigenous design and development effort made for grid connected operation and most importantly the special design features incorporated to ensure a very high degree of safety and protection so necessary in the rural areas with predominantly non-literate users. The paper is concluded with some important lessons learnt from both the technical and logistics point of view for guiding installation of similar such plants in the remote rural areas in India and other developing countries in the future.
